PROCESS OF TREATING MATCH-SPLINTS.

No Drawing.

To all whom it may concern: f

Be it known that I, WILLIAM A. FAIR- BURN, a citizen of the United States, and resident of Short Hills, in the county of Essex and State of New Jersey, have invented certain new and useful Improve- ,ments in Processes of Treating Matchand the latter agent rendering the splints non-glowing when the flame is extinguished. In carrying out my invention I provide a liquid bath comprising at least two superimposed immiscible liquids of different specific gravity, into which the match splints are dipped to a sufiicient depth and for .a suflicient period until the splints are properly impregnated with the constituents of the liquids. The properties of these liquids are such that one provides or serves as a vehicle to transmit the flame from the ignition head-composition of the match to the body of the splint, and the other liquid provides or serves as an incombustible agent to render the splint non-glowing after the flame has been ignited and extinguished.

Preferably the sub-liquid is a flaming agent comprising an organic oil which is insoluble in an alcohol, a d the super-liquid is an alcoholic solution ofa non-combustible substance, such solution being of less specific gravity than th oil and thus floating upon the top of the latter.

Efficient results are attainable by the use, for example, of cotton seed oil as the flaming agent, and a two per cent. solution of boric acid in methyl alcohol as the non-glowing agent. Splints subjected to this bath dry readily; they are not greasy; they are very inflammable, and they are well impregnated with the non-glowing material.

In pursuance of my invention, the oil is poured into a suitable tank, and the alcoholic solution is then floated on the oil, the depths of the respective liquids being such as to permit the dipping of the splints vertically to a substantial extent in both liquids.

Application filed October 23, 1912. Serial No. 728,079.

Ordinarily a layer about one-half inch deep of the alcoholic solution will suffice; the depth of the sub-stratum of oil being such that verticallydisposed splints may be dipped thereinto about one-half inch.

When my invention is used in connection with the manufacture of matches upon a continuous match making machine of the type wherein the splints are inserted row by row in an endless carrier and thereby held in spaced relation to each other and transported through the match-making path, the tank containing the superimposed liquids is suitably located beneath the route of the car rier, so that the depending splints on the latter during their travel toward the headcomposition applying devices can be dipped into and subjected to the action of the bath until the efficient impregnation of the splints with the respective components of the bath shall have been attained.

I do not limit myself to the use of the specific liquids herein described nor to the specific relation of one liquid to the other; as my invention, in its broad aspect, contemplates the use of any superimposed immiscible liquids of different specific gravity whichrespectively impart to the splints dipped therein the flaming and non-glowing characteristics hereinbefore mentioned.
